Pokerstars deposit

I've made a deposit at pokerstars thinking that they will double the amount I deposited but so far that hasn't happened. I've used the bonus code STARS600 when I made the registration. Do I need to clear the bonus before it is credited to me?

Just wanna add: You should ignore that you even have a bonus, and do not even try to clear it. If you do, you might end up playing too many tables/too long sessions/too high stakes and make a big loss, bigger than the winnings from that bonus. Just play your A game and the number of tables you are used too
This does not mean that you should play without bonus, extra money is always good^^ just don't get too greedy, depending on game (SNG, tournament, cash) and limits it is quite hard to get the full bonus cleared (they usually come in smaller bits anyway)
